The purpose of this study was to compare the shear bond strength of veneering porcelains(Duceram Kiss, VITA VMK Master) to 3 types of Co-Cr cores manufactured with different methods(casting, milling, 3D printing). Cast(StarLoy C, Degudent, Germany), milled (Ceramill Sintron, Amann Girrbach, Germany), 3D printed(EOS Cobalt Chrome SP2; EOS GmbH, Germany) Co-Cr core specimens were fabricated according to Schmitz-Schulmeyer method. Two kinds of dental porcelains(Duceram Kiss, VITA VMK Master) were applied on Co-Cr cores, with each core given 12 specimens of each porcelain respectively, thus in total 72 specimens were fabricated. Shear bond strength of each specimen was measured by universal testing machine(Z020, Zwick, Ulm, Germany) and scanning electron microscope (JSM 6360, JEOL, Tokyo, Japan) was used for observing fracture pattern in 20 magnification. Shear bond strength according to different manufacturing methods were analyzed using SPSS 21.0(IBM SPSS Statistics 21, IBM, Chicago, USA) in one-way ANOVA. Duncan’s multiple range test were conducted as a post-test.(p=0.05)
Shear Bond strength of Duceram Kiss veneered groups were as follows: milled(29.78±4.67 MPa), cast(29.29±5.84 MPa), 3D printed (26.58±4.78 MPa). Results of VITA VMK Master veneered groups were as follows: milled (29.08 ±4.60 MPa), 3D printed(27.24±4.28 MPa), cast(26.23±2.92 MPa). Yet both groups had no significant difference (p>0.05). All specimens in the test groups exhibited combined failure of mixed cohesive and adhesive failure.
